. i Application inea April To ZZ whom t may concern:

Be it known that I,` Gnoizcn K. LIGHT, a citizen ot the United States, and a resident of the city of N ew York, borough of Brooklyn, in the county of Kings and State ot New YorkJ have inventedL a .new and inproved Pumpinp` Device, of which the following is a iull7 clear, and exact description.

This invention relates to pumping devices, and has particular reference to a simple and eiiiciently operated pump ot the rotating type.

pump which in a simple and eilicient man ner causes a constant flow or liquid through the pump as a result oit' a new application of the centrifugal action taking place in the rotating' receptacles. n

Another object of the invention resides in the provision of means `whereby the operation oi the pump requires an Xpenditure of 'a minimum amount of power and comprises apparatus which is composed of a minimum number of parts. p

further object resides in the particular construction and ar angement of Vparts hereinafter described and claimed and shown in the accompanying drawings.

The invention, in general, comprises a receptacle with which a siphon is associated to establish a normal liquid level in the receptacle. Means are provided for rotating; the receptacle so on the liquid tends to alter and reduce the level of the'liquid within the receptacle in such a manner that the siplionic action is started and tends to renew or restore the disturbed or altered level. rthis action results in the continuous introduction of liquid into the receptacle in a. constant stream. The liquid is discharged from the receptacle by reason of the fact that the centrifugal action resulting when the receptacle is rotated causes the liquid surfaces to be disposed in lines parallel to the sides of the receptacle, whereby the liquid climbs the walls thereof until it reaches a suitable outlet, from which it is discharged. By reason or' the momentum initially imparted to the liquid, and by reason oi the automatic action of the Siphon to introduce new liquid into the receptacle, the operation of this device requires the expenditure ot a constant and small amount of power. The simplicity of the device in its structural features makes it "Specification of Letterslatent.

An object of the invention is to provide a that the centrifugal actionv highly advantageous and efficient in operation. The invention ings', of which Figure l is a partial vertical longitudinal section taken through the pump receptacle; a horizontal section taken on the is illustrated in the drawrig. 2 is line 2`2 of Fig. 1.

The drawings illustrate onexforin which my invention in its application and comprises a tank n 1 containing;` a suitable quantity of water the level of which is indi- 2. This tank may be any suitable size but provision may be made to supply a constant amount of water thereto, while the pump is in operation. this tank 1 an arm 3 cfa siplion depends, the other arm l oi which is adapted to project downwardly into the pumping receptacle 5. The arm t passes through a plug or closure portion 6 in the top of the receptacle 5 and tits therein in a. reasonably snug manner. The bottom of the 1ecept'acle is closed and connected to a shaft 7 having' thereon a lpulley 8 which is driven by a belt 9 con-` nected to any suitable In a manner usual lower end ofthe arm a lower level than the 3. The siphon having` beenv filled in the usual manner, the water from the tank l iiows into the receptacle 5 until a level 10 is established therein equal to the level 2 in the tank l. Disposed vertically along the source of power.

Z1- of the siplion is at walls within the receptacle 5 are a plurality of blades 11 which extend from the inner face of the receptacle 5 'radially toward the center thereof. These blades extend only part oit the way toward the cent-er, and the ends of the blades are spaced a suitable distance from the surface of the arm et of the siphon. rlhese blades may be disposed within and connected to the receptacle in any suitable manner (not shown). The upper end of the receptacle is provided with apertures 12 leading to a chamber 13 having,- a pipe connection 14 as an outlet there` trom.. A bearing flange 15 is provided on the upper end of the receptacle 5 which cooperates with a similar bearing 16 on the closure portion 13 by means of ball bearings 1.7 to permit the rotation of the receptacle-5 with respect to the closure portion 13 with a minimum amount of Vfriction therebetween.

in siphonic. actions, the c lower end 'ofthe arm f of the 'blades' l1 on than would be Assuming that the siphonic action rhas taken place to an extent necessary to establish the equal levels 2 and l() above mentioned, whenV the receptacle liquid will tend to rotate with the receptacle, and this rotation is assisted by the action thefliquid, tending to carry it around with much less slopping the case'V it the ybladesV were not in a receptacle. By reason ot thetact that these blades extend vertically along the inner walls of the receptacle and radially into the receptacle from the walls, they rdo .j not assist in lit'ting the water but merely level.

'trifugal action will tend to '10 ofthe liquid ;v and as promote the eil'ective rotation of the 'water with the receptacle. 'As soon as the rotation oi the receptacle commences, thef cenalter the level the speed ot the receptacle increases, the liquid initially in the vreceptacle will assume a position with its surface parallel to the walls of thereceptacle. This will result' in the loweringA or alteration of the original level l0, whereby the siphonic action introduce more It will be observed, therefore, that by this Y i 5 is rotated theA i into and disposed longitudinally construction l have provided a pumping de vthe parts whereby its 4operation is e'liected. By reason of the centrifugal action on the liquid, jthe normal level of the liquid is altered,` and this action in combination with the siphon which automatically comes into operation upon the alteration of the normal level, results inr thepump requiring aV mini mum expenditure of power to produce a constant stream of liquid which may be forced to any desired height.

lVhat l claim is:V f

1.- A- pumping device comprising a verti cally disposed rotatable receptacle, a plurality or radially extending blades extending longitudinally within said receptacle, discharge openings at the upper end ot' said receptacle, and a Siphon associated with said receptacle, the longer arm of said siphon extending adjacent the bottom ot said receptacle whereby when the normal level of the liquid within the receptacle is altered by the rotation 'of the receptacle the siphon will immediately supply more liquid to thereceptacle.

Q. A pumping device tablepipe vertically disposed, a plurality oi and radially extending guide the upper end of blades therein, a hood over dissaid pipe adapted to receive water charged therefrom, rality oit discharge apertures in its upper end adjacent the hood, a siphon arm extending into said pipe, the lower end of the arm being disposed adjacent the bottom ofthe receptacle, and means for rotating said pipe.
